However, numerous brains studied were contributed because family members suspected their loved ones had CTE, which could potentially make the study bias.
CTE is still not completely understood by health professionals, but other possible signs and symptoms may include depression or apathy, substance abuse, suicidal thoughts or behavior, irritability, aggression, trouble swallowing, vision and focusing problems, and trouble with sense of smell, according to Mayo Clinic. "These findings suggest that CTE may be related to prior participation in football and that a high level of play may be related to substantial disease burden".
The Journal of the American Medical Association published a report Tuesday that found chronic traumatic encephalopathy, or CTE, was diagnosed in 177 former players, or almost 90 percent of brains studied.

But Mithali praised her team-mates for their show in the World Cup and blamed inexperiece for their defeat in the summit clash. Then the dramatic collapse happened, with India losing seven wickets for just 28 runs to be all out for 219 runs in 48.4 overs.
An updated study published Tuesday by the Journal of the American Medical Association found that 110 of 111 brains of deceased former National Football League players had chronic traumatic encephalopathy. All the participants were exposed to a relatively similar type of repetitive head trauma while playing the same sport. They are one of the most frequent brain injuries, occurring more than 1.5 million times a year in the United States; 100,000 of these injuries occur in football alone, at the professional, collegiate, and even high school levels.
However, it is unknown if CTE and Alzheimer's are related. A post-mortem study of his brain showed that he had been suffering from CTE. Consider this: If they live long enough, most men will develop prostate cancer, even though they probably won't die from it.
In brains afflicted with CTE, "the issue is when tau is deposited in high amounts in an abnormal area".
One important caveat, however: the study's findings are susceptible to selection bias, since the only brains eligible to use were donated by families specifically because the former player showed signs of CTE. Although professional leagues like the NFL have begun to put into place new rules created to reduce the frequency of concussions among players, the risk to athletes at any level (professional, collegiate, high school, and even pee wee) remains great.
